Error message on upgrading of "iTunes+QuickTime" as prompted by Apple Software Update: "iTunes + QuickTime" has an invalid signature. The download has been removed.
Okay. With that one, perhaps try a repair install of Apple Software Update, as per the following document:
How to repair Software Update for Windows
Now restart the PC, and try launching ASU again. Does it grab the iTunes update properly now?
Thanks for the reply, but that did not work.
I tried downloading the itunessetup.exe directly from both apple.com and filehippo.com, but I was still getting an error about an invalid signature. After checking the box that I mentioned above about allowing to install even when the signature is invalid after I launch the itunessetup.exe file nothing happens. No processes are added to taskmanger... nothing.
This is really a huge issue for me as I was on iTunes version 7.3.2 and updated my video iPod to 1.2.2. Now none of the songs display on my iPod. I know this is an issue related to the fact that I don't have the latest iTunes version, but I can't upgrade my iTunes. I've tried upgrading to iTunes 7.4 but to no avail. I encounter the same problems that I do when I try and update to 7.5.
